DRAW-SHAVE.

SPECIFICATION forming part of Letters Patent No. 325,759, datedSeptember 8, 1885.

Application tiled July fl, 18H5.

.To @ZZ whom t may concern:

Be it known that I, WILLIAM MILLsPA'UGH, of Middletown, in the county ofOrange and State of New York, have invented certain new and usefulImprovements in Draw-Knives and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in draw-knives. l

The object is to provide a draw-knife in securely adjusted at any angleto the knifeblade in theplane of the said blade and readily detachedtherefrom for packing or other purposes.

With these ends in View my invention consists in certain features ofconstruct-ion and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a View of the knife withhandles adjusted for ordinary use, one of the handles being in section.Fig. 2 shows the handle in a convenient adjustment for grinding theknife. Fig. 3 is a detached view of the knife-blade, and Fig. 4 is adetached view of the concave-faced washer.

A represents the knife-blade, constructed in curved form, as is usual,and provided with the cutting-edge c. The ends of the blade A are ofcircular form, as shown at B, and are provided on their curved vedgeswith series of saw-tooth projections I).

The above construction of the blade admits of forming it of solid steel,and as tlie tangs for securing it to the handle are formed separate theblade can be made from the solid steel cheaper than it can be forgedvfrom iron and steel, as is commonly the case.

The tangs C are provided with bifnrcated heads, the branches of whichembrace the sides of the circular ends B,- and are pivotally securedthereto at the centers of the circular ends by pins orrivets c. Thestems of the tangs C are screw-threaded, and adapted to engagestationary nuts D, located within the handles E. The handles E are ofordinary form, and are provided with cap-ferrules e. The socket ends ofthe handles are thus made perfectly smooth, and form seats for the bases(No model of solid concave-faced washers F, interposed between thehandles and the ends of the blade. The washers F loosely surround thetangs, and the curves of their concave faces conform to the curve of thecircular ends B. Thus when the threaded end of the tang is in engagementwith the stationary nut within the handle the washer B may be forcedinto contact with the sharp teeth on the ends B by turning the handle.

As several of the teeth simultaneously engage the concave surface of thewasher, the handle is secured thereto in a firm manner and with butslight exertion upon the screw, and by unscrewing the handle a veryshort distance it may' be swung outwardly or inwardly at pleasure.

The shifting of the handles at different angles to suit different cutsis well known to be a decided advantage, and the turning of the handleinto a position ina line with the blade, or nearly so, enables theperson holdingV the knife on a grindstone to exert his pressure toadvantage and hold the edge steadily in the desired position. Theremoval of the handles for packing purposes is alsoa feature calculatedto lessen the cost of the article.

The projections on theends .Bare represented and described as saw-toothprojectionsg but while the form shown is considered the most desirable,on account of the fine degree of adjustment which it allows and the easewith which a firm contact is established, I do not wish to limit myselfstrictly to that form of projection, as they might be formed withrounded points, or even flat points, and at might be left perfectlysmooth. I would have it understood, therefore, that I do not wish to4limit myself strictly to the construction herein set forth, but reservethe privilege of making such changes as fairly fall within the spiritand scope of my invention. j

Having fully described my invention, what I claim as new, and desire tosecure by Letters l. The combination, with a blade provided with roundedends, of threaded tangs pivotally secured at the ycentersof the roundedends, and handles adapted to engage the tangs roo l and turn into lockedadjustment against the edges of the rounded ends, substantially as setforth. l

2. The combination, with a blade provided with rounded endshaving teethVYor projections on the edges, of threaded tangs pivotally secured atthe centers of the rounded ends, and handles provided with femalescrew-threads adapted to engage the threaded tangs, and thereby move thehandles into and out of looked adjustment with the toothed edges of therounded ends, substantially as set forth.

3. The combination, With a blade provided with oireularshaped endshaving sharp teeth on their edges and threaded tangs pivotally securedat the centers of the circular-shaped ends, of handles adapted to serewon the tangs, and concave-faced washers located be-
